摘要： The present invention discloses a system and method of generating frequency coherence between a received reference positioning signal transmitted by at least one reference transmitter and a unique positioning signal generated by a positioning-unit device. A positioning-unit device is a specialized transceiver capable of receiving and interpreting reference positioning signals from the reference transmitter, another positioning-unit device or both. The positioning-unit device receives a reference positioning signal and measures a frequency offset in the received reference positioning signal relative to a common oscillator. Once a frequency offset is measured, the positioning-unit device adjusts a frequency steerable clock by an amount derived from the measured frequency offset. The positioning-unit device then generates a unique positioning signal, which is aligned with the frequency steerable clock. Furthermore, the positioning-unit device continuously adjusts said unique positioning signal by applying the measured frequency offset to the frequency steerable clock, which is referenced to the common oscillator. Subsequently, the frequency of the adjusted unique positioning signal is aligned with the frequency of the received reference positioning signal.

摘要： A plasma arc torch and method for improving the life of the consumable parts of the plasma are torch, including the electrode, the tip and the shield cap. The method includes turbulating gas as it flows over the exposed surfaces of the electrode, tip and shield cap to increase turbulence in the hydrodynamic boundary layer of the gas flow, thereby enhancing convective heat transfer. The result of enhanced cooling is improved consumable parts life. For example, to increase the turbulence of the gas flow over the outer surface of the electrode, the plasma arc torch electrode has a roughened, or textured outer surface formed with dimples, axially extending grooves or spiraling grooves formed in the outer surface of the electrode. The inner and outer surfaces of the tip and the inner surface of the shield cap are similarly textured.

摘要： A positioning system that includes a plurality of chronologically synchronized Time Division Multiple Access (TDMA) Positioning-Unit Devices and a position receiver incorporating a TDMA Adaptive Directional Antenna Array is disclosed. The plurality of chronologically synchronized Positioning-Unit Devices, positioned at known locations, transmit positioning signals in a predetermined Time Division Multiple Access (TDMA) sequence, such that each Positioning-Unit Device has a unique transmission time slot. The TDMA Adaptive Directional Antenna Array is configured to consecutively steer a directional receive antenna in spatial synchronization with the plurality of Time Division Multiple Access (TDMA) Positioning-Unit Device transmissions, such that the directional receive antenna is oriented toward the currently transmitting Positioning-Unit Device, or the directional receive antenna is oriented toward the origin of the currently received positioning signal. The TDMA Adaptive Directional Antenna Array is controlled by a deterministic algorithm based on the knowledge of the Positioning-Unit Device locations, TDMA Adaptive Directional Antenna Array location, TDMA Adaptive Directional Antenna Array attitude, network Time Division Multiple Access (TDMA) transmission sequencing, Positioning-Unit Device positioning signal propagation delays, and network time.

摘要： A positioning system that includes a transceiver (hereafter termed a Positioning-Unit Device) that receives one or more reference positioning signals from other Positioning-Unit Devices and/or from other qualified reference positioning signal sources. Each of the received reference positioning signals preferably has a carrier component, a pseudo-random code component, and a data component. The Positioning-Unit Device generates, in response to the received reference positioning signals and their known locations, a unique positioning signal. The unique positioning signal has a carrier component chronologically synchronized to one or more of the carrier components of the received reference positioning signals, a pseudo-random code component chronologically synchronized to one or more of the pseudo-random code components of the received reference positioning signals, and a data component chronologically synchronized to one or more of the data components of the received reference positioning signals. Once a Positioning-Unit Device is chronologically synchronized to a reference transmitter other Positioning-Unit Devices entering the network can use its transmitted unique positioning signal as a reference positioning signal. The geographical distribution of these chronologically synchronized Positioning-Unit Devices creates a time-coherent network of positioning signals that propagate a reference timebase over a substantial geographical area. The positioning system also includes a roving position receiver. The roving position receiver can generate code-based single point position determinations by making range measurements for each of the received chronologically synchronized pseudorandom code and data components, and can generate carrier-based single point position determinations by making range measurements for each of the received chronologically synchronized carrier components. The formation of a chronologically synchronized positioning network allows a roving position receiver the ability to autonomously calculate both code and carrier-based single point position solutions without the requirement for differential correction or absolute time accuracy within the network.
